Radial engine run up

[AryanKnight]

~What'th, -when shooting a nifty bird like this'en, --please try to provide us the entire enchilada, -that is to say to include the initial start-up like this one here on Utube--> [ " R-1340 radial engine start - Mayocraft P-26 aircraft "] --paste into above search-box..!!

[jx14aby]

that thing looks fun to fly

[jawsrock1]

Is this at the Auburn Airport? It kinda looks like it and I think I've seen this plane there.

[vigi86]

beatiful baby!

[NMoulana]

wow that plane looks quick, couldn't weigh more than 1800 pounds.

[duragg]

Yak 50.

Very close on the empty weight. I think it is 1690.

[imdicatf]

radial rocket

[yakovlev3a]

what plane is this?

[duragg]

Yak 50, 82-2308.

Overhauled by Nerka in 2002 or so.

Bunch of hot-rod mods since I have owned it here in USA.

[yakovlev3a]

how much did that yak50 cost you?

[duragg]

... everything!

Lots of mods over the years with far too much "invested".

[yakovlev3a]

i guess what i meant to ask was, without the mods.....if i wanted a plane yak 50 how much do people usually pay for it?

[raganriley]

@duragg But i bet its worth it

[tractorboy8420]

if it was all silver and had the bell cover housing it ould look verry similar to the H1-racer! you know the "seemless" racing plane built by Howerd Hughs! (i doubt i got the name right) and landed in a beat field ! haha he said that it would still go faser evend though he had to crash it..

[Woodsballer209]

Wow, what a beauty!

[pilotguy191]

is that Tom Johnson?

[duragg]

Good point.

Amended title.

[MrSidneywhitaker]

Very humble reply, and more dignified that the redneck!

[MrSidneywhitaker]

Why do you have to be so offensive and foul-mouthed? If you are about to fly, this is the "start-up". Do you want to see it rotate slowly? Look at the cut-away model from San DIego Air and Space Museum, submitted by "petervisor".

[Ignantredneck]

huh?

[ljubisa88]

Thank you, dude, only AVGAS!!

[ljubisa88]

which type of fuel it burns one man said his standard recommendation for any radial

is to burn a mixture of 75% unleaded mogas and 25% 100LL.

This gives a lead content equal to leaded 80/87 octane avgas,

any more than this is overkill

[duragg]

100LL Aviation fuel only. Nothing else. Never any MOGAS for sure. We need the higher octate, and more importanly MOGAS is not stable over long periods of time (plus it stinks).

[P214Stearman]

Yak-50?

[Pablo221sp]

yeahh!!!

it´s very sound!!!

great airplane!

[driftability]

sexy

[lejink]

thats a pretty airplane u have there

[duragg]

Not when they have high compression pistons, gapless rings, super-alloy valves, Mang-Bronze guides, intake and exhaust seals, NGK plugs, 8mm wires, custom supercharger impellers, etc...

[orangecounty60]

how does it fly??

[TheOneAndOnlyFink]

Very carefully.

[tinymouse2]

How efficiant are radial engines over standerd engines?

something ive been wanting to find out for a while

[lotusiotus]

radial engines get 500000 MPG (lol)

[GeneralSirDouglasMcA]

I've been wanting to know the advantages/disadvantages of a radial engine over standard engines too.

I love how radial engines sound like warplanes, the unique sound.

[tinymouse2]

Hehe

thats because most planes that were proppeller driven used radial engines ^_^

Some weren't but it was traditional to be

[vigcs]

They have a few advantaged and a few disadvantages. One advantage is that they can literally run (not well) with an entire cylinder blown off...which came in handy with WW2 fighters and bombers.

However, they're exremely expensive to maintain and run. For example...a lot of the old radial bombers had 50 gallon oil tanks because the radial engines leaked oil so damn bad.

[chopperdanny13]

Radials also were lighter and more reliable than their liquid cooled counterparts. The Navy preferred them because of their reliability, compactness (short noses meant more planes parked on a carrier) and power output. Anyone that ever flew with a P&W 2800 called it the smoothest running engine ever. Yes, they use lots of oil-- but that also keeps them cooler running.

Downside, when not running, the oil pools in the bottom cylinders, requiring oil scavenging pumps.

[theberengersniper]

Some nice information there. Why do radial engines use a lot of oil?

[Joelm940]

I was attending flight school and we flew a Cirrus Sr20 wich had a flat/Boxster six engine wich is similar to car engines, but laid flat. at the Refueling station at the Airport I saw an old plain with a radial and it made a beautiful sound when it turned on.

[gschjetne]

Radial engines get really good air cooling, even with many pistons. That's why they were popular in high-power applications.

For low-power applications (that haven't been taken over by the turboprop yet) a 4 or 6 cylinder boxer is much easier to work with and can still get adequate air cooling.

[tinjah1]

very nice

[iliketojumplargeobje]

what a beautiful machine!

[Scanvest]

Hey, what plane is that? Looks stunning!

[duragg]

It is a Yak 50. Russian built in the 1970s and 1980s. I have since rebuilt the engine and should update this video.

[Scanvest]

Oh yes, now I recognise it! Sweet machine! Thanks! I love piston-engined warbirds and acrobatics planes.

Sound has no equal!

[jimmybillabela2000]

sounds very healthy! That plane looks competely refurbished and I bet he's hangin to have a fly...!! Great stuff!! Very compact airframe compared to the engine, built for one thing...speed!

[ciobanuaddy]

What plane is this ???

[zxj13708380359]

That'very nice！

[mbitsko25]

That plane looks like it really dislikes sitting there in one place.

[eggtoc]

Very nice!!

[bumblebike]

Nice setup!
